i GAS BURNER.

Applicationrnled December 29, 1921. Serial No. 525,677.

To all iU/tom it may concern.'

Be it known that I, h/lnrrrnis lnnesrnn hun, a citizen of the UnitedStates, residing at Cleveland, in the county oit' Cuyahoga and State otOhio, have invented certain new and useful Improvements in Gas Burners,of which the following is a specilication.

rlhis invention relates to gas burners, and has for its object .toprovide an improved burner suitable for use in gas furnaces and otherheaters; or it may be attached to gas pipes in household rooms. Thestructure is believed to provide a burner of increased eiliciency ascompared to other burners for the purposes referred to.

lin the accompanying drawings, Fig. 1 is a vertical section olf theburner. Fig. 2 is a top plan view. Fig. 3 is a section on the line 3 -3of Fig. 1.

ln the ligures of the drawings, 1 indicates a vertical gas pipe havingan air opening 3 through which air is admitted into the pipe to mix withthe gas therein. The upper end of the pipe is provided with a cap 4lhaving a row of line jet holes 5 around the same.

is initially ignited at these holes.

Surrounding the head of th pipe, and spaced therefrom, is a drinn 7supported by a bracket 6 on the pipe 1, this drum being closed at thetop by a plate 8. The side wall of the drinn has a series of jet holes10 around the same, and on the outside et the drinn, above these holes,are upper and lower circular lins or 'flanges 9 and 9, the upper [lange9 being somewhat wider than the lower lange.

Surrounding the burner thus constructed a larger circular shell 12,supported by brackets 11, and this shell has a top plate 13 providedwith openings 14s therein controlled by a rotary damper 15 mounted ontheplate 13 and having openings which may be registered or not with theopenings in the top plate. The damper plate may be turned by a handle16.

In the operation of the device, the gas is lirst lighted at the holes 5,and this iills the drinn 7 with mixed air and flame, the shell beingopen at the bottom, and after the drum becomes sufiiciently heated thegases formed will also ignite and burn at the jet holes 10, producinganother llame between the drinn 7 and the shell 12, and this llame isdeflected by the battles 9 and 9a against the shell 12, and inconsequence the air both inside and outside the shell 12 is heated to ahigh degree. The initial combustion at the jets 5, being confined withinthe drinn 7, forms a gas or product in combination with the air admittedat the bottom of the drum 7, which will burn at the openings 10. lnother words y it is assumed that the combustion in the drinn 7 isincomplete and is completed by union or the products with the additionalair entering the lower end of the shell 12 when the products of theinitial combustion escape through the openings 10. Repeated operation ofthe device has demonstrated the 'einen ence or flame both within thedrum '7l and'in the space between the drinn and the shell 12, and thishas been found to give a superior heating capacity in proportion to theamount or gas used. l

l claim:

1. A gas burner comprising a pipe head having jet openings, a drumsurrounding said head, said drum being open the bottom and closed at thetop, the side wall of the drinn having ball'les on the outside thereofand jet openings below said ba'l'lies, and a shell surrounding the drinnand spaced therefrom.

2. A burner comprising a pipe head having et openings, a drumsurrounding the head and spaced therefrom, the side wall oil the drinnhaving et openings and spaced batlles above said openings, and a shellsurrounding the head, said shell being open at i the bottom andhavingopenings at the top, and a damper controlling the top openings. lntestimony whereof, l anis my signature in presence ot two witnesses.
